  • 提出了两种圆环型微波电谐振结构,这两种谐振结构分别与金属线进行适当的组合形成电磁耦合单元,对正入射的电磁波产生谐振响应并具有强烈的吸收作用.通过对两种耦合单元的电磁仿真和优化计算使其各自获得最佳的吸波性能.在微波段8—12 GHz利用自由空间法对这两种耦合结构的电磁特性(即反射系数S11和透射系数S21)进行实验测量,在10.7 GHz和10.07 GHz吸收率分别达到95%和98%以上.
    In this paper, two kinds of ring-type microwave electric resonant structures were proposed, which were appropriately assembled with metal wires to form electromagnetic coupling units. The coupled structures have resonance response to the incident electromagnetic wave, and absorb the electric and magnetic fields strongly. We simulated these two kinds of coupled structures, and then optimized the simulation results to achieve the best absorption properties. The electromagnetic properties (the reflection coefficients S11 and the transmission coefficients S21) of metamaterial absorber sample were measured using free space method in microwave frequency from 8 to 12 GHz. At 10.7 GHz and 10.07 GHz, the absorptivity reaches 95% and 98%, respectively.
